Vizio 37L suddenly stopped getting all digital channels

With the same antenna that has been working fine for months. The analog channels still come in just fine, but after a storm the other day, the TV isn't picking up digital at all anymore. Any suggestions??

I had the same problem with my 42" vizio. Was working fine for about a year and a half, then a month after all stations went digital, I couldn't see any digital channels and it wouldn't scan for digital signals
This is a strange go around, but it worked for me. . Tried unplugging, pushing power button for two minutes... did everything the forums suggest, with no resolve. But, here's what DID work for me. Trust me, it sounds strange, but it continues to work (and, yes... it's not a permanent fix... the channels still go out once in a while, but I can always get them back now)
Use your Vizio remote control. Turn your TV on. Press the "input" button until you get to "RGB", which is what you would connect a computer to. Make sure no computer is connected, or it's at least off if it is connected. When you get to RGB, you'll see a message that says "No Signal". After about 5 seconds, the TV will enter a sleep mode and seem as if it has turned off (orange Vizio logo). Once it completes it's little sleep cycle and "clicks" off, wait a few seconds and hit the input button again. It'll go to the next menu item. Keep clicking input until you're back on "TV", and VUALA! The channels are back!
I accidentally figured this out when trying to troubleshoot, but I'm glad I did. Didn't want to dishout $250 to get it fixed. Let us know if it works for you too!

wow.... thanks for sharing this information. It worked for me too. Actually had TV apart, was going to replace main board.... or just get a new TV. wonder what it is scientifically that brings the tuner back. anyway, glad I ran across your post! thanks, man.wow.... thanks for sharing this information.

The following is from Vizio Tech Support and it totally worked when the other ideas on this site didn't.

"I recommend clearing the TV memory, resetting the settings and re-running the scan.

To perform this please remove the cable connection and run a channel scan to clear out the existing channels.

Once this is finished please perform a power cycle on your TV. Please follow the steps in this order:81- Power off TV2- Unplug TV from outlet3- Press and hold in the power button on the TV for 30 seconds (while it is unplugged from the wall) 4- Release the power button 5- Plug in the TV into a different outlet6- Power the TV back on

There is also a factory reset option in your menu under the SETUP section. It will say either "reset all settings" or "system reset". I would recommend this option as well.

Once the power cycle is finished and all settings are reset. Plug the cable line back in and run the channel scan."
If I did it again i probably wouldnt "reset all settings", I would try the scanning section first and see what happens. You can always go back through all of the steps if doing only part of it doesnt work.

Definitely took care of my problem. Been frustrated for a month, gave multiple theories a try but this one did the trick. Thankfully, was about to trash it.Definitely took care of my problem.

The RGB technique for me worked on my four year old TV. EXCEPT, once the Vizio turned orange, I had to use the power button on the TV to get it back on. Once it powered up, I hit Input on the remote to get back to the normal TV. Then, all the digital channels Appeared!!!! YES! Thanks a bunch!

I tried all these and they didn't work. only way I got it to complete a scan was to remove the cable and start a scan. Once the scan got past where it was hanging, I reconnected the cable and it completed.

if you have a cable hooked to it,then you need to pay for a cable tv subscription,you cannot get free digital channels on it,you shouldnt get any analog channels unless a station hasnt changed to digital,you need a cheap hdtv antenna to receive digital channels over the air.

That may not be correct. You would not lose all your digital channels. Vizio has an un-addressed problem with losing digital stations. Multiple threads are posted due to this problem, which is why I am on this site. I have lost all digital stations on CATV connection. The Toshiba set in the next room is getting over 150 DTV channels, the Vizio, only analog. Zero Digital.
